Description

The American bittern is a medium-sized heron with a long, thick neck and a long, pointed bill. It is a solitary bird, mostly nocturnal bird that keeps itself hidden amongst dense vegetation. It is more often heard than seen with the male producing a distinctive booming sound that can be heard for several miles around.

It is well-camouflaged with brown, buff, and white streaked plumage. The side of the neck has a blue-black patch which is larger in the male than the female. It has brown cheeks and a buff supercilium and moustachial stripe. The bill, legs, and feet are yellow-green coloured.

When alarmed American bitterns they stand motionless with the bill pointing upwards which helps them to blend into the background.
